1. Introduction
Agriculture is one of the leading sectors for developing as well as the developed world, which is a basic sector of the national economy. The best way to impede food calamities is to invest in the agriculture sector [
1]. A World Bank Organization report [
2] summarized that a country should be more successful with faster growth by linking the agriculture sector with other sectors. In Pakistan, the agriculture sector is the primary source of livelihoods and ensure food availability to rural and urban residents. It also provides raw material to the industrial sector and enables the country to earn foreign exchange through exporting the finishing goods [
3]. The Pakistan agriculture sector consists of five sub sectors such as livestock, fisheries, major crops, minor crops, and forestry. The major crops are cotton, wheat, sugarcane, rice, and maize and the minor crops are bajra, jowar, gram, barely, and tobacco. The major crops accounts for 25.6 percent in agriculture value addition and it contributes 5.3 percent in Gross Domestic Product (GDP) whereas the share of minor crops in agriculture value addition is 11 percent and it contributes 2.3 percent towards GDP. Additionally the contribution of other sub sectors like livestock, fisheries and forestry also have a meaningful contribution in GDP of Pakistan [
4].
Additionally, the Government of Pakistan, GoP (2017–2018) [
3] emphasized that the agriculture sector has a dominant role in the overall economy; its share is 18.5% to gross domestic products and employed 38.5% of the total labor force of the country. The agriculture sector performance can boost the overall economic growth and a smart source for the eradication of rural poverty. Over the last decade, the performance of agriculture is not promising mainly because of the deteriorated production of all essential crops.
Currently, the agriculture sector of Pakistan is facing many challenges such as unpredicted changes in climatic factors, continuous increase in temperature, changing patterns of rainfall, emission of CO
2, water shortage, lack of improved seed and advanced technologies, and shortage of finance to secure the basic inputs for agriculture production [
5]. Pakistan has a strategic location in the South Asia region and attracted many developed countries to invest in different sectors of the economy, but unfortunately, despite much importance of the agriculture sector, it was always neglected in terms of foreign direct investment [
6]. Subsequently, foreign direct investment (FDI) had a crucial role in accelerating the growth of the agricultural sector by filling the gaps in investment and technology, which were mainly raised due to limited sources of income and credit [
7]. Accordingly, Krugman [
8] states that FDI has the distinctive feature which focuses on resource transfer and sustaining a high-level investment. Therefore, the Pakistani government has taken steps to attract foreign direct investment by providing special incentives so that the agricultural sector gets benefits from technological spillovers and ensures an increase in production and growth. Such FDI inflows trends in different developing countries showed significant role in enhancing economic growth, boosting technological level of country and created huge employment opportunities [

12].
Pakistan and China relish handy and responsive relations since the establishment of diplomatic relations in May 1951. Over time, the relationship has bloomed into an all-weather strategic cooperative partnership. In 1978, both countries constructed Karakoram Highway, a construction miracle linking the mountainous Gilgit Baltistan with western China. Investment from China in Pakistan started from the 1980s and both countries signed an agreement for the protection of investment in 1989. Both countries signed many agreements to develop tourism, infrastructure, bilateral trades, and different investment projects in Pakistan. After 2013, investment from China suddenly boosts up because of the investment in the projects under the China Pakistan Economic Corridor. Through this project, China has invested about 46 billion US dollars in Pakistan to strengthen the economy by the construction of modern transportation networks, numerous energy projects, and a special economic zone. China is one of the top FDI investors in the world and the single largest investor in Pakistan in the recent last decade [
12]. According to the Lahore chamber of commerce and industries (LCCI), agricultural technology has now been introduced to the agriculture sector of Pakistan by China Pakistan Economic Corridor (CPEC). According to this plan, the agricultural technology would be transferred to the agro-chemicals, pesticides, seeds, and fertilizers. This plan would be helpful to educate farmers and with latest machinery; farmers can give more agricultural output with better quality [
13].
Since the last two decades, the agriculture sector growth of Pakistan’s economy has been severely devastated due to unpredicted climatic changes. Continuous increase in temperature, a series of floods from 2010 to 2014, long span of droughts, and occurrence of new pests and diseases has greatly affected the agricultural production [
14,
15]. It is worth noting that climatic changes declined the agricultural production and solemnly threatened the food security of the country. Uncontrollable changes in climatic scenarios disturbing the livelihoods of all stakeholders related to the agriculture sector severely damaged the infrastructure and created many difficulties in innovating new and advanced technologies for combating the adverse impact of climate change on agriculture sector [
16].
By considering all the above facts, the adverse impact of climate change and the lower growth rate of the agriculture sector, FDI seems to be an effective solution to stabilize and enhance the growth of the economy, particularly agriculture sector growth. Pakistan’s agriculture sector has enough potential to support the overall economy; however, the lack of foreign investment and negative influences of climate change and CO2 emissions are restraining agricultural productivity in the country. Therefore, the agriculture sector emphasizes the need to revisit the investment pattern in which FDI could be an essential determinant or input.
In Pakistan, a number of studies focused on the relationships between FDI and the growth of GDP with different techniques, “such as [
17,
18,
19,
20].” While some researchers examined the role of FDI in different economic sectors of Pakista (Ali and Asghar [
21] and Ullah [
10]), not a single study was conducted to check the specific effect of Chinese FDI with climate change and CO
2 emissions on the agricultural sector of Pakistan. The reason for exploring the effect of Chinese FDI is that in the last decade, China has invested a huge amount in different sectors of Pakistan’s economy, so it is worthy to estimate its impact on the least growing sector (agriculture) of Pakistan. Thus, this study is a new attempt to investigate the impact of Chinese FDI, Climate Change, and CO
2 emissions on agricultural growth of Pakistan.
Figure A1 in
Appendix B shows the inflow of foreign investment in Pakistan from abroad for the fiscal years 2001–2017, which indicates that the USA, UK, and UAE were leading investor countries from 2001–2012. From 2013, however, while Mainland China is a leading investor country.
Figure A2 in
Appendix B shows the inflows of sector-wise foreign direct investment in Pakistan from 2001–2017. Data shows that the agriculture sector is getting a little amount of FDI as compared to other sectors in the study. Sectors of communication, power, mining and quarrying, and oil and gas are the favorable sectors to attract significant inflow of FDI.
To take an excellent view of FDI in the agriculture sector, it is imperative to interpret the government policies to attract a comprehensive amount of FDI into the sector. To the best of our knowledge, no empirical study has been investigated in the context of Pakistan to investigate the flow of FDI from Mainland China and its impact on agriculture sector growth. This paper aims to investigate the impact of Chinese FDI and causality among the variables in the context of Pakistan. This paper highlights the overall structure of the agriculture sector and major constraints in the progress of the said sector. Finally, this paper suggests policy implications for the progress of the agriculture sector.

2. Literature Review
This study aims to empirically examine the effect of Chinese investment, CO
2 emissions, and climate change effects on agricultural growth of Pakistan. In economics, growth has been considered a burning topic. Many theories propose to highlight the factors affecting growth, such as Keynesian theory, classical theory, neo-classical theory, and endogenous growth theory [
22,
23,
24]. Theories determine those factors which are attracting more FDI, such as Keynesian theory 1930, primarily focused on total spending on the economy and its output, where the economist concentrated on government policies and intervention to prevent an economic recession. Solow [
23] outlines that the technological process is an essential factor in stimulating the growth of economics. According to the theory, continuous progress in technology could achieve long-run economic growth, while the neoclassical growth theory suggests that the labor, capital, and technology are important factors to bolster the economy.
Dickey [
25] determined that FDI not only increases the investment level or capital stock but also pushes economic growth. Quattara [
26] explores that the affiliation of foreign aid has adverse effects on domestic savings in the context of Côte d’Ivoire. Public infrastructure and FDI together lead to economic growth as the study conducted by Ridzuan et al. [
27] examined the role of FDI in three main pillars of sustainable development, like economic growth, environmental quality, and income distribution. They applied Autoregressive Distributed Lag Model (ARDL) and concluded results that show the inflow of FDI push to higher economic growth enhances environmental quality and disparity in the case of Singapore. Similarly, the case of Pakistan Javaid [
28] concluded that FDI is a positive determinant to enhance the gross domestic product and further added that the main issues are high population growth rate, low income, low savings, and burden of external debts. Hence, FDI is a powerful tool to overcome these issues and to promote economic development [
21]. The report regarding “Foreign Direct Investment for Development“ published by Organization for Economic Co-Operation and Development (OECD) in 2002 suggests that FDI influences growth by raising total factor productivity, and it proposes the appropriate policies for host countries. In the meantime, FDI prompts technology spillovers, backing human capital formation, contributing to international trade integration, and it supports to create a more competitive business environment as well as enhance enterprise development. Additionally, FDI helps to improve environmental and social conditions in host countries by transferring cleaner technologies [
29].
China is the largest FDI recipient country in the world and a single huge investor in Pakistan by using annual time series data from 1980 to 2014 with ARDL bound testing approach. Hussain and Hussain [
12] concluded that market size of China, its inward FDI, and direct investment in Pakistan have a positive and significant impact on the inflow of FDI in Pakistan.
The higher inflow of investment in the agriculture sector leads to the meaningful contribution of a country’s economic growth. The study conducted by Ogbanje et al. [
30] analyzes the performance of the agriculture sector with the inflow of direct investment from abroad in Nigeria. Similarly, Oloyede [
31] shows a positive influence of FDI on the agriculture sector of Nigeria in both the short and long run. Epaphra and Mwakalasya [
11] applied the classical linear regression model to conclude the affiliation between FDI and agriculture value-added, they found that FDI does not impose any effect on the agriculture sector in the case of Tanzania.
Iddrisu [
32] used the Johansen Cointegration test to elucidate the long and short-run association of FDI on the performance of agriculture sector in Ghana from 1980 to 2013 and concluded that the impact of FDI was negative on the productivity of agriculture in the long-run, but in short-run there was a positive impact of FDI on agricultural productivity. In some countries, the relationship between FDI and agriculture was shown as positive, “such as [
30,
33].” For example, in Nigeria, the investment from FDI to agriculture boosts the production of this sector; however, the government always ignores the development of agriculture. Osifo [
34] elaborated on the role of direct investment from abroad in different sectors like agriculture, manufacturing sector, service sector, and contribution of these sectors to the overall growth of the economy. The results from the Robust Standard Error Model concluded that the role of FDI in the agriculture and manufacturing sector is significant, and both sectors contribute to economic growth. Osifoet all further added that the manufacturing sector is advantageous and poses a vital role in economic growth.
The agricultural FDI has u-shaped relationships in the long term. FDI in agriculture will promote the agricultural gross total factor productivity (GTFP) in the short-run. However, it will inhibit the growth of agricultural GTFP after a certain critical point [
35]. In response to Chinese FDI in Western Africa, Fofana [
36] investigated the contribution of Chinese foreign investment in agriculture sectors and economic growth of West African countries and concluded that Chinese FDI is supporting agriculture, domestic investment, and economic growth.
Environmental pollution, climate change, and global warming are the harmful emission of carbon dioxide and has a positive and essential relationship with the agricultural-environmental system [
37]. According to the report written by the Lahore University of Management, London School of Economics and Political Science, World Wide Fund for Nature Pakistan, the change in climate pattern has negative impacts on agricultural productivity. Moreover, in 2014, the German Watch Index declared Pakistan is among the world’s top 10 vulnerable countries regarding climate change. GoP [
38] states that the weather conditions and climate changes are not stable, which are the biggest challenges for the economic sectors of Pakistan, particularly for the agriculture sector. These changes decrease the water resources, and insufficient water is harmful to agricultural productivity. The study conducted on 20 agrarian commodities in different regions [
39] investigated that the influence of climate change differs in diverse regions. Many climatologists found that climate change negatively affects agricultural production in some regions but promotes in other areas. Kaiser [
40] found that climate change is increasing the risk for the agriculture sector, while Janjua et al. [
41] states that climate change leads to a high temperature, which affects water availability that may be a critical factor for wheat cultivation in the future. The estimated results from Vector Auto regression (VAR) model suggested that there is a negative relationship between climate change and wheat productivity.
The immediate development in agriculture and mechanization of the agronomic industry caused significant growth in the consumption of energy and CO
2 emission as per study outcomes, and the long-run result showed a positive relationship between CO
2 emissions and cropped area, energy use, fertilizer off-take, gross domestic product per capita, and water availability, while there is a negative relationship between improved seed distribution and total food grains [
16]. Climate change in Pakistan is basically produced by the emission of greenhouse gases and human activities such as urbanization, industrialization, transportation, agriculture, livestock, and energy use [
42]. It is proved that climate change and CO
2 emissions linked with agricultural productivity because the agricultural sector is an important source of carbon dioxide emission. It is very important to decrease the emissions related to the agriculture sector and extend low carbon agriculture, which is necessary for economic development and to control the environment and energy [
43,
44]. According to the World Resources Institute’s Climate Analysis Indicator Tool (WRICAIT) the contribution of agriculture in greenhouse gas (GHG) emission is 41% of total GHG emissions. Achieving sustainable economic growth without any adverse effect on the natural environment is crucial these days. Demissew Beyene and Kotosz [
45] shows that the long-run association between the economic growth and CO
2 emission is not as Kuznets assumed (an inverted-shape), but instead of bell-shaped which means that the relationship between GDP per capita and CO
2 emission is negative until the GDP per capita reaches to a certain point and once it reaches to a certain point the relationship between the stated variable is positive. The study conducted in the USA for the period of 1960–2013 by Dogan and Turkekul [
46] to investigate the relationship between CO
2 emissions energy consumption, real output the square of real output, trade openness, urbanization, and financial development by using ARDL bound testing approach and Vector Error Correction Model (VECM) revealed that the main source of CO
2 emission is energy consumption in the USA and urbanization also has a positive impact on CO
2 emission. Dogan et al. conducted the study to investigate the validity of Environmental Kuznets Curve (EKC) hypothesis for the MINT (Mexico, Indonesia, Nigeria, and Turkey) countries and pointed out that the environmental Kuznets curve hypothesis is valid for each of the MINT countries and the anthropogenic pressure on the environment is because of fossil fuel energy consumption, exports, urbanization, and financial development [
47]. Moreover, Moutinho et al. [
48] confirmed that the negative changes in CO
2 emission in the last decade is because of the financial development and productivity of renewable sources like renewable electricity generation per GDP.
Attracting FDI is the central issue for all countries. Countries that have improving physical and financial infrastructure attract more FDI than others [
49]. Multinational Firms are investing in other countries to get advantages based on low factor cost and low trade cost, the availability of cheap labor and extensive local market encourage foreign investment in a host country, charitable institutions, and well infrastructure also attract FDI in developing countries. Based on factors like political stability, property rights, and corruption, investors decide to invest in host countries where low corruption and stable economies attract more FDI [
50]. It’s commonly proved that inflows of FDI lead to economic growth, but the economies with high growth also attract more inflows of FDI, hence the high economic growth is a potential factor to attract more investment volume in host countries. Higher economic growth and business-friendly environment with the internal size of the market and balance of trade are essential elements to attract inflows of FDI [
51].
Countries with a higher GDP growth rate and advanced infrastructural setup are attracting more FDI as compared to low GDP growth economies [
52]. Jadhav [
53] focused on the factors that are attracting more FDI, consist of economic, institutional, and political factors in BRICS countries (Brazil, Russia, India, China, and South Africa) results confirmed that economic factor is a powerful determinant to attract more investment in the above countries because most investors are promoting by market seeking purpose. Other factors, such as institutional and political factors, are unable to attract a significant amount of FDI. Bernanke and Gürkaynak [
54] narrate foreign direct investment is a vital aspect of building capital in developing countries since the flow of foreign investment in developing countries is a powerful tool of economic growth.
As an Indian News Paper, the Economic Times [
55] reported that China is investing in different sectors of Pakistan for market seeking opportunities. Sino-Pak Economic Corridor known as (CPEC) is the largest megaprojects ever undertaken in terms of Chinese foreign direct investment. The actual cost of Sino-Pak Economic Corridor is to be expected at 75 billion US dollars, out of which 45 billion-plus US dollars will be invested in the corridor, which will be functional in 2020. The rest will be invested in different projects like infrastructural development and energy in Pakistan. The construction of Gwadar international airport, seaport, and expansion of the Karakoram highways are also part of this mega project. Karakoram highway connects China with Pakistan in Beautiful Gilgit Baltistan, which is the gateway to this mega project. This project will create employment opportunities for the whole of Pakistan, which is a positive sign for Pakistan to decrease the unemployment rate in the region.
5. Conclusions and Recommendations
Agriculture is the backbone for the entire economy of Pakistan; it plays an essential role in the economic growth and development process. The primary purpose of this empirical study is to investigate the role of Chinese foreign direct investment, climate change, and CO2 emission from 1984 to 2017 on agricultural growth of Pakistan in the short and long-run. For stationarity of each variable, we have applied ADF and PP test. The results of these tests confirmed that none of a variable is stationary at the second difference I(2); however, our study variables are stationary at the level I(0) and at first difference I(1). Once it’s confirmed that our variables are stationary at I(0) and I(1), we have employed ARDL bound testing technique and Granger Causality test (VECM) to find the causality among variables in short-run and long-run.
Empirical findings reveal that CFDI in the agriculture sector has a significant and positive influence on the agricultural productivity of Pakistan. However, the slight value of coefficient stated lower marginal influence on agricultural growth. The lower coefficient of Chinese foreign direct investment in our study shows that the agriculture sector is receiving less Chinese foreign direct investment among other sectors of Pakistan. The decisive role of Chinese foreign direct investment in the agriculture sector shows that concerned authorities take necessary steps to boost investment in the sector. So, the concerned authorities in the government must ensure sufficient investment in the sector and take the steps needed to attract more FDI in the agricultural sector.
On the other hand, climate change and CO2 emissions are not supporting agricultural growth both in short-run and long-run associations. The reason behind the negative impact of climate change on agricultural growth is changing weather patterns; the temperature is increasing continuously. Climate change is a big environmental challenge that is affecting all economic sectors in the country and especially the agriculture sector. The government of Pakistan already took some initiatives on the adverse impact of climate change; however, the government should show much more concern about this issue to protect agriculture, which is the backbone for the overall economy in Pakistan because its contribution has an essential role in the GDP of the country and this sectors absorbs about 45 percent of total labor force. The government should adopt strategies to minimize the negative influences of changing climate and CO2 emissions, which would be helpful to agricultural production as well as the growth of the economy. CFDI caused the boost of agricultural production in Pakistan, while climate change and CO2 decreases productivity. However, the exporters of agricultural products failed to compete in the world market. It is the responsibility of the government of Pakistan to encourage exporters and provide necessary services and adopt friendly policies towards agricultural products exports.
Finally, the Granger Causality results indicate that there is strong long-run and short-run causal relationships in some variables, as the results show a bidirectional relationship between agricultural growth (AGG) and employment in the agricultural sector (AGEM). Based on the Granger Causality test results, the government of Pakistan should take into account the importance of agricultural exports, agricultural employment, and GDPPC to increase the agricultural productivity of Pakistan.
While the above analysis provides interesting insights in ARDL, Bound Testing, and Causality test, it should be noted that the development of efficient environmental policies likely to reduce temperature and CO2 emissions is necessary to increase productivity in the agricultural sector. The government should adopt specific policies to help agricultural producers to improve agricultural productivity by advancing farming technologies and provide basic inputs with approved quality (scientifically improved seeds, fertilizer, and effective pesticides) and local governments should observe and regulate the irrigation system for producing quality output with efficient utilization of resources so they can compete in international markets.
The study also has some limits in terms of access to data and included few variables for the analysis. Historical data for FDI before the 1980s has the reliability issue due to a lack of documentation. For future research, researchers can extend it to the provincial level with the most recent data and can devise the most influential policy at the regional level because some provinces such as Punjab and Sindh are specialized in agricultural production.
